14 Claims. (Cl. 220-32) This invention relates to a combination wall fuel oil vent and llreceptacle for basement tank installations in heating systems burning fuel oil.

The object of the invention is to provide a simple and novel receptacle adapted to be fitted in the wall of a building and to receive and support the filling and vent pipes connected with the fuel tank, usually in a basement, and prevent the entrance of cold air into the building thereby preventngcondensation of moisture into the tank and having means to cover and protect as well as seal the filling pipe while permitting the vent to remain open to the atmosphere so that the fumes from the oil may escape and still avoid an unsightly appearance and tampering with the pipes. f

Another object of the invention is to provide a device of the above character which may be conveniently Vapplied in connection with buildings beingrerected or already built by occupying the Yexact spaceV ofl a number of bricks or other masonry construction, as well as applied to a frame building, instead of requiring that the wall be chopped out or drilled, as in connection with the objectionable and unsightly installation heretofore in vogue, the present device serving to eliminate exposed ugly pipe ttings and providing a device which is simple inconstruction,l easy and economical to manufacture and which serves to prevent malicious, spurious or misohievious tampering with the pipe or connections thereof, dropping articles into the tank through the pipe, or setting the same on fire', to prevent children swinging on the pipes or the same from becoming loose, as Well as avoiding projections beyondV the building line and staining of Walls from rust and scale requiring repainting of same as well as the pipes.

Further objects and advantages will appear and be brought out more fully in the following specication, reference being had to the accompanying drawings, in which: Y

Fig. '7 is a view similar to Fig. 1, but showing a modification of the device applied to av wooden or frame building; and

Fig. 8 is, a .horizontal section taken onthe line -vof Fig. 7. s

Referring to the drawings, and particularly to Figs. 1 to 6 inclusive, I0 designates a brick or masonry wall of a building having anopening, preferably rectangular in shape, in which a metallic receptacle or box is tted and occupying the exact area of a number of bricks or blocks composing said wall structure usually above a cement or otherv foundation and secured in position as Well as sealed around the same by the mortar. Thisv box includes'a top wall II, a bottorn wall I2, and side Walls I3 forming a rectangular structure having an open back I4 in line with Vthe inside of the wall. The front Wall is designated atV [5 and these various walls are secured together in a complete unitary structure as by Welding or otherwise. The bottom portion l2 is flush with the front edges of the other walls andV the Wall structure of the building at the bottom portion and the upper or top portion I6 of the front wall I5 is inclined so as to slope back `in rear of the front edges of the top and side wallsproviding an offset and aY space in Whichcertainparts are accommodated as will be later described. This set back wall portion I6 has as hole Il and carries an internally threaded boss or ring I8 at the inside corresponding in diametei` to thesize of the hole I1 and the size of an inclined filling pipe I9. This pipe is externally threaded adjacent its outer end, as at 2li to engagevthe threaded boss I8 and project outwardly of the wall portion I6 a short distance perpendicularly thereto within the space formedby the sloping wall portion I6. The pipe I9extends downwardly and inwardly at a slight inclination to insure the ow of oil and draining thereof into the tank when lling the latter and may be connected by a fitting 2| on the externallythreaded inner end of the pipe I9 inside of the wall I0 and shown as an elbow for connection to a pipe 22 which leads to `the tank for storing oil consumed in the heating system. K

A removable inclined hood or cover 23 is provided over the projecting end of the filling pipe I9V parallel to the inclined or sloping Wall portion I6 and is in the form of a metallic plater which closes and seals the open end of the pipe I9 and forms a protective hood against the entrance of,

moistule, dirt or other foreign particles as well as tampering or dropping articles into the pipe and in fact prevents access thereto unless the cover or hood is removed. This cover or hood has a top iiange 24 at an obtuse angle adapted to fit beneath the top Wall II and side flanges 25 designed to t within the side walls I3 so as to close all sides except the open bottom 26 which places the space thus enclosed in communication with the atmosphere. In order to secure the cover or hood 23 in position it is provided with suitable means for locking it While permitting convenient removal thereof, preferably in the form of a hasp structure. As shown, this includes a depending apertured arm 21 welded or otherwise rigidly secured to the inner face of the cover 23 in a plane at right angles thereto and projecting down at an acute angle below the open end of the hood and bottom edge thereof closely adjacent the portion I5 of the front wall where it is suitably apertured. A shoulder 28 is provided on one face of the hasp arm 21 and for support engages the top edge of an apertured hasp lug 29 similarly apertured to register with the aperture of the arm 21 to receive a padlock 30 thus sealing and locking the hood against the end of the filling pipe so as to prevent access to the latter. A similar but smaller internally threaded boss or ring 3I is provided at the other side of the box over a smaller hole 32 in the wall portion I5 spaced apart on either side of the transverse center of the receptacle or box. The hole 32 receives a vent pipe 33 which is smaller than the filling pipe I9 and has its externally threaded end screwed into the boss 3l, but engages or abuts the wall I6 around the hole 32 which is made of the same size as the bore of the vent pipe 33. This vent pipe is similarly threaded to take a fitting or elbow 34 depending upon the location of the storage tank and has a pipe 35 connected thereto and leading to the tank for venting the fumes of the oil to the outside atmosphere from beneath the hood or cover 23 and the opening 26 at the bottom thereof. Thus, due to the fact that the vent pipe 33 stops at the wall portion I 6, the vent pipe is not sealed by the cover` 23 as is the projecting end of the filling pipe, but left freely open at all times.

In order to prevent insects, dirt or moisture in inclement weather, entering the vent pipe, as well as preventing access thereto or dropping articles into the tank through the vent pipe by those maliciously or mischieviously inclined, provision is made for closing the vent port. For this purpose, angular guide plates 36 are provided on the sloping top portion IS of the front wall at either side of the` opening 32 forming a guideway or groove 31 for a screen 38 which may be retained in position by a stop lug 39 at the bottom. A defiecting plate 40 may be provided on the wall portion I6 above the screen to prevent rain Water from running into the vent pipe and protect the same when the cover is 01T for filling the tank through the port of the filling pipe I9.

When the device is installed in a wall and the pipe connections are made at the inside, the box may be filled with rock wool, balsam wool or other non-rusting insulating material 4I which Willseal the box against the entrance of cold air to the inside, as well as eliminating the possibility of any heat loss through the metal or condensation of moisture running down into the oil in the tank. Strips or lathing 42 may be provided at the inside of the wall and over the open inner end of the box serving as an anchoring for plas- 75 ter 43 or cement at the inside for further protection and appearance. By having the box or receptacle open at the inside ush with the inner face of the wall of the basement, it is apparent that when the pipes are put in place, the entire inside of the receptacle can be conveniently filled with the insulating material and pipes are indiscernible from this point.

In Figs 7 and 8 of the drawings, a modification is shown adapting the device for wooden or frame buildings in which the construction is the same as heretofore described, except that in this case the wall 44 has an opening cut therein in which the box may be mounted as previously described. However, the front wall is provided with a surrounding ange 45 projecting outwardly of the walls II, I2 and I3 and fitting against the building wall 44, as well as limiting the displacement of the receptacle into the Wall of the building from the outside. The inclined upper portion I6 of the frontwall I5 is slit as at 46 by cutting or severing the metal in the form of a channel or inverted U-shaped form to produce the depressed upper wall portion I6 which slopes back and is ecured to the inner faces of the top and side walls by welding, or in any other suitable manner as previously described. The receptacle is then secured in position by suitable fastening means, such as screws 41 passed through apertures in the flange 45 outwardly of each of the top, bottom and side walls of the receptacle and into the building wall 44. Otherwise the device is the same as heretofore described in connection with Figs. 1 to 6 of the drawings.

In the use of the device, it is only necessary to unlock the padlock 30 and remove the hood or cover plate 23 at pipe I9 so that the nozzle from the supply truck tank may be inserted therein or connected to the threads 20 for filling the tank through the pipe I 9. Fumes will escape through the vent pipe 33 and when the storage tank has been filled, the hood or cover 23 is reapplied and locked to close the filling pipe while still permitting free access to the outside atmosphere through the vent pipe 33 at the screen or foraminous cover 32, the space beneath the hood or cover 23 and between it and the front wall portion I6 due to its angular formation with the bottom portion I5 at obtuse angles and the opening 26 at the bottom of said hood space. In this way the parts are protected in inclement weather and a very sightly appearance is provided compared with the old arrangement of pipes which project beyond the wall and tampering is prevented in addition to preventing exposure of the parts to rust or damage, and thereby greatly facilitating the filling of oil storage tanks as employed in heating systems or the like.

While I have illustrated and described thev preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from 'the spirit of the invention. I, therefore, do' not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
